ACROLEIN - RELEASING COPOLYMERS |
摘要 |
Acrolein copolymers prepared from acrolein and one or more polyhydric alcohols, which will release monomeric acrolein in an aqueous system and hence have a prolonged effect on microorganisms. The copolymer is prepared by adding acrolein to a reaction medium containing one or more polyhydric alcohols and a catalyst in dissolved form, while not allowing the temperature of the reaction medium to rise above 50.degree.C. The acrolein-releasing copolymer may be used in aqueous systems as a biocide.
